Though his fight against a Miami drug cartel gives him a chance to get his old job back, Marshal Raylan Givens (Timothy Olyphant) returns to Kentucky to clear his name as a lawman and continue working on cases closely tied to his past.

As his ex-wife Winona Hawkins (Natalie Zea) jeopardizes them both with her ill-advised efforts to solve her own financial crisis, a struggle for control of Harlan County’s criminal enterprises pits Raylan’s dad, his old friend Boyd Crowder (Walton Goggins) and the members of a matriarchal crime family against one another and the law in a violent war.

As the plight of a teenage girl whose father’s murder has left her at the mercy of his killers and a coal company’s heartless efforts to exploit the county’s poverty-stricken residents draw everyone into the center of a deadly storm, Raylan and Winona struggle with questions about their future together.
